(but his own opinion, I should add, is against the supposed 
difference of the species,) ‘the other distinctions between the 
thick and thin-billed Nutcrackers are the greater strength of 
the feet and claws of the former, a circumstance noticed by 
Brehm, who described them as two species, under the names 
of the long and short-billed Nutcrackers, and the different 
form of the white mark at the end of the tail, which in 
‘Nucifraga caryocatactes’ is much straighter than in ‘Nucifraga 
brachyrrhynchus.’ This, with the other distinctions which I 
have mentioned, obtain more or less in all the specimens I 
have had an opportunity of examining.’
